This deep galaxy field from Webb’s Near-Infrared Camera (NIRCam) shows an arrangement of 10 distant galaxies marked by eight white circles in a diagonal, thread-like line. Two of the circles contain more than one galaxy. This 3 million light-year-long filament is anchored by a very distant and luminous quasar. Ccalled J0305-3150, this quasar appears in the middle of the cluster of three circles on the right side of the image. Image credit: NASA / ESA / CSA / Feige Wang, University of Arizona.
